And lastly, love this book! Who would thought I would pick this up? Another random pickup. I've been literally just going on Goodreads and they've been recommending me some bomb ass books. This book is... I love it! I love this book. Read this book, it's great, you'll feel great reading it. [...] It's just a lovely story and I highly recommend it
